Default 94 Buick Park Ave Engine Woes

Hi guys. I have a 1994 Buick Park Avenue 3.8L First Series. The car had been sitting in the drive way for a year and hadn't been turned on. About a month ago I bought it out of retirement. It needed a new tire and a new battery and that was it. Started right up. I got the oil changed, put some STP in the gas tank and filled the tank up. I got the oil changed 2 weeks ago. I was running an errand today and it started making this terrible knocking noise. The dashboard said there was so NO oil at all in the engine. I pulled over and checked the oil and it was full. I drove it back home since I was about 5 mins away. Now the car won't even start. My neighbors insist its an oil problem. The engine sounds as if it'* not getting oil. My neighbor thinks that the fuse that controls the oil is blown. I don't know where to find this fuse or what number it could be. Does anyone know the number and the location so I can check for myself? If it'* premature to think that its a fuse that is causing this, what else could it be? Thanks for the help...

BTW: This car has 60,000 miles. Plugs and wires are good.

The oil pump is mechanical, so there is no fuse that would prevent the engine from getting oil.

We have seen a couple cases in which the oil pressure sending unit has shorted & blown the fuse. That fuse also supplies power to the fuel pump & ignition control module. Needless to say it won't start if that fuse is blown. Check fuse #6 under the dash on the passenger side.

I didn't know there was a fuse box on the passenger'* side. I'll look to see if it blown tomorrow.
